Hm, you can make a "Confirmations Thread" like the one on RotK. Someone does something they know gets them points? They post the link to the thread in the confirmations thread along with a quick note as to what it is that they've done that needs points. That way rather than looking through the entire site, you can just go to the confirmations, click the link, and go straight there. Save you the hassel ultimately of having to dig through posts.
